My partner and I are looking for a shallow water boat. We want to avoid a jet, if a tunnel hull, such as used by the Florida flats skiffs, will do [almost] as well.

The experts on this board can help me by describing the approximate dimension of tunnels on hulls they are familiar with.

For example, a boat made in Oregon offers a tunnel 8" high by 18" wide. Since a typical prop is 12-13 inches in diameter [not including skeg], 8" does not seem adequate. A friend in Texas told me his Kenner's tunnel was 4" high. Seems too little to me.

What tunnel dimensions are used by Hewes and Hells Bay Boatworks in Florida area?
